I thought I would start a thread about what weird behaviors your fish have.

My new (I've had him less than a month) betta Vega has two funny habits. The first is that likes to sit on the top most leaf of his silk plant like he is going to rest, then he scoots himself off the leaf slowly and free falls to the bottom of the tank. He then loops around the bottom of the tank and repeats. It's the strangest thing I think I have seen a betta do but he seems to enjoy it.

The other habit he has is he likes to swim in the current made by the filter. He also likes to bite at the water coming into the tank off the lip of the filter. I've heard other users on here say their betta's like to swim in the filter currents too.

I just thought I would share and wondered if other users have observed their fish doing strange things.

captain flares at his heater and tail slaps his thermometer :s he also likes to burry his self in a flower I made him and will just barely poke his head out. I have a thread about it somewheres.... Patty likes to cuddle with cory cats and they love her.

Little Pearl is still wondering if I'm not as scary as she thinks I am, and is learning quickly that my cat is one of the most interesting things she has ever seen, because she's most likely never seen a cat before in her life.

Both my fish seem to think inanimate objects in their tank are their mortal enemies. Dol's constantly tackling his thermometer and the leaves of his big leafy plant. Morpheus for some reason enjoys tackling his cave. Weird :S
